碳纤维混凝土智能桥梁研究

Research on Intelligent Control of Carbon Fiber Reinforced Concrete Intelligent Bridge

由于超静定结构在温度变化条件下产生结构应力、应变,相应提出一种智能桥梁——在梁底布设短切碳纤维混凝土层。经理论分析和算例表明,该方法在很大程度上抵消了荷载作用下产生的弯矩和挠度,并可实现智能控制,从而提高了桥梁的承载能力和变形能力。

In this article, static-indeterminant concrete structure will generate structure stress and strain by change of structure temperature. It proposes a kind of related intelligent bridge control methods： deploy short carbon fiber reinforced concrete in the bottom of the beams. The theory analysis and evaluation of proposed models show that this method largely offset the structure moment and deflection under load; it is able to achieve intelligent control, thereby raising the hearing capacity and deformation capacity of bridges. This method for multi-span continuous beam is very effective.
